Question

I have run into a problem… I have a pair of checkboxes that I have named and numbered. I need to get the checkboxes marked and insert them into my database. Here is how I am creating the checkboxes:

<div class="check"><input type="checkbox" name="acharge1" value="1"> <span style="color: #0C0">$$</span><input type="checkbox" name="amenities1" value="1">Amenity 1</div>
<div class="check"><input type="checkbox" name="acharge2" value="1"> <span style="color: #0C0">$$</span><input type="checkbox" name="amenities2" value="1">Amenity 2</div>
<div class="check"><input type="checkbox" name="acharge3" value="1"> <span style="color: #0C0">$$</span><input type="checkbox" name="amenities3" value="1">Amenity 3</div>
<div class="check"><input type="checkbox" name="acharge4" value="1"> <span style="color: #0C0">$$</span><input type="checkbox" name="amenities4" value="1">Amenity 4</div>

Some of these will be checked and some wont. Also they will not always be checked in pairs, but I have to upload them in pairs to my database. So in other words: acharge1 and amenities1 will not be checked but acharge2 and amenities2 will be. So I tried a foreach loop and that did not work. I also tried a while loop, but I did not know what to check. So this is what I have now:

$aa = 1;
    echo "Amenity: ".$_POST['amenities'.$aa];
    $aa++;
    while(isset($_POST['amenities'.$aa])){
        $amen = $_POST['amenities'.$aa];
        if(isset($_POST['acharge'.$aa])){
        $acharge = $_POST['acharge'.$aa];
        }else{
            $acharge = "0";
            }
        echo "Amen: ". $amen." charge: ".$acharge;  
        mysql_query("INSERT INTO hotel_amenities (amenity_code, hotel_id, charge) VALUES ('$amen','$hotel_id','$acharge')") or die(mysql_error());
        echo $aa;
        $aa++;
        }

But as you can see this does not work, because if amenities1 is not checked it will not do the while loop through the others. Anyway ANY help on how I can achieve this would be greatly appreciated!

EDIT** This is the concept, so as you can see that sometimes they money box will be checked with the amenity and sometimes it will not.

The way you are going about this is entirely wrong. If you are unsure of the number of options available, you should write it like this:

$cnt = 0;
foeach ($_POST as $option => $value) {
    if (preg_match("/(?:acharge|amenities)(\\d+)/", $option, $matches)) {
        $cnt = max($cnt, intval($matches[1]));
    }
}
for ($i = 0; $i < $cnt; $i ++) {
    $amenity = $_POST['amenities' . $i];
    $value = "0";
    if (array_key_exists("acharge" . $i, $_POST)) {
        $value = "1";
    }
    mysql_query("INSERT INTO hotel_amenities (amenity_code, hotel_id, charge) VALUES ('$amenity','$hotel_id','$value')") or die(mysql_error());
}

I think this would do it for you. That is assuming you have established the connection previously and taken care of the value for $hotel_id.
